Influence of Prefabricated Building Incentive Policy on Project Implementation Effect

To promote the development of prefabricated buildings, China's provinces (autonomous regions and municipalities) have successively issued guiding documents for the development of prefabricated buildings, specified their own development goals and various incentive policies. Although various provinces (autonomous regions and municipalities) have put forward various incentive policies, there are differences in the actual development of fabricated buildings. Therefore, this paper studies the impact of the incentive policies of fabricated buildings on their project implementation effect through correlation analysis. After coding the selected research samples through text analysis method based on the perspective of policy instruments, the distribution of the three types of policy instruments, namely supply-type, environmental-type and demand-type are counted respectively, and then the incentive policies of the provinces (autonomous regions and municipalities) are quantified through policy scoring. After selecting three evaluation indexes for correlation analysis, it is found that the type of policy tool most used at present is the environmental-type, followed by the supply-type, and the demand-type accounts for the least. And the highest policy score among all provinces is Jiangsu province. Through the above analysis, it can provide reference for provinces (autonomous regions and municipalities) to optimize or innovate the existing incentive policies, and promote the development of fabricated buildings.
